I hate it when I hit back to check something and loose a post.
Anyway:
"You're right, they are oddly dark. Isn't there a nice shiny 'chrome' setting in that program? The scattering armor especially should have a mirror-like surface."
Lighting problem, that IS shiny metal. Working on it.
"The two armors look pretty good except for the darkness problem."
Good..which would you prefer? Given that this is a Version of another image, we don't need THREE of the things
"The scattering armor looks better but is still not what I had imagined. The little hexagonal 'pyramids' should fit together with no spaces between the facets. No 'flat' armor surface should be there at all, only angled 'shiny chrome' surfaces."
Can do. I think I'll reduce the # of facets too, that lets me get the armor looking a little less thick.
"Can you make one of those 'armor' shapes transparent like the crystaline armor is?"
Yup.. pick one.

Lighting may be an issue but I'll see what I can do.
